Scissor Stabilizers Diagonal Retracted Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scissor stabilizers for telescopic lifts and handlers face limitations in stabilization performance, particularly when operating off-road or on uneven terrain, due to constraints in road travel width and ground clearance, which affect the vehicle's ability to maintain horizontal stability and navigate inclines.
Innovation Solution
The design of scissor stabilizers with telescopic arms and a support frame that allows the arms to be arranged diagonally in the retracted configuration, reducing the hinge points and increasing the ground clearance, enabling a greater lifting height and improved stability on uneven surfaces while maintaining a reduced transverse dimension for road compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the arms are arranged horizontally in the retracted configuration to comply with road travel width rules, then the transverse dimension is reduced, but the ground clearance is insufficient and the angle of attack is limited
Solution Approach 1:
The patent applies dimensionality change by transitioning the arm arrangement from a horizontal configuration (single plane) to a diagonal configuration in three-dimensional space. This spatial reconfiguration allows the arms to achieve both compact transverse dimensions for road compliance and sufficient ground clearance for off-road capability, effectively resolving the contradiction between width constraints and clearance requirements.
2Adaptability or versatility
If the arms are extended to increase the lifting height and stability on uneven terrain, then the vehicle versatility is improved, but the transverse dimension exceeds road travel width restrictions
Solution Approach 1:
The patent implements dynamics by designing the stabilizer arms with telescopic capability that allows continuous adjustment between retracted and extended states. This dynamic configuration enables the vehicle to adapt to different operational requirements: maintaining a compact transverse profile for road travel while extending the arms to achieve greater lifting height and stability when working on uneven terrain, thus resolving the contradiction between versatility and width constraints.
3Stability of the object's composition
If the distance between the centers of rotation is increased to improve vehicle horizontality during stabilization, then the stabilization performance is improved, but the transverse dimension in retracted configuration increases
Solution Approach 1:
The patent resolves this contradiction by utilizing three-dimensional diagonal arrangement of the arms in the retracted configuration. This spatial reconfiguration allows the centers of rotation to be positioned at optimal distances for achieving vehicle horizontality during stabilization, while the diagonal orientation projects less transverse dimension than a horizontal arrangement would require, thus simultaneously improving stabilization performance and maintaining road compliance.
